BOTTLE-CLOSURE.

Specification of Letters Patent.

Patented Nov. 5, 1907.

Application filed April 20, 1907- Serial No. 369,316.

To all whom it may concern:

Be it known that I, J on S. HAWKINS, a citizen of the United States, residing at Highlandville, in the county of Christian and State of Missouri, have invented certain new and useful Improvements in Bottle-Closures, of which the following is a specification.

The present invention has for its object to provide a novel form of valve mechanism which is designed to be placed in the neck or outlet portion of a bottle or like receptacle in order to prevent the refilling of the receptacle after the original contents have been withdrawn.

The invention also aims to provide a peculiarly constructed valve mechanism of this character which not only operates at all times to prevent any liquid from being forced into the receptacle, but also forms a manually operated means whereby the bottle can be sealed to prevent evaporation or accidental spilling of the contents.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a vertical sectional view through the neck of a bottle having the improved valve mechanism applied thereto. Fig. 2 is a similar view showing the bottle neck in an inverted position. Fig. 3 is a detail per spective view of the valve mechanism.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The invention is shown as applied to a bottle neck as indicated at 1 and the said neck is provided at a point near its base with an inwardly extending annular flange 2 defining an outlet opening 3. Slidably mounted within the neck 1 above the flange 2 is a pair of spaced disks 4 having central openings therein constituting valve seats. These disks 4 fit accurately within the neck of the bottle so as to prevent any liquid from being forced around the edges of the same and are connected by means of the rods 5 so that they move in unison and are rigidly held a fixed distance apart. Cooperating with the central valve openings in the disks 4 are the outwardly opening valves 6 which are forced upon the valve seats when an effort is made to force a liquid into the interior of the bottle or receptacle, but fall outwardly to permit the outflow of the original contents of the receptacle. Pendent from each of the valves 6 is a stem 7 which passes through the valve opening in the disk 4 and operates to prevent lateral displacement of the valve and to cause an accurate seating thereof. In order to limit the outward movement of the valves 6 cages or keepers 8 are located upon the upper faces of the disks 4 so as to engage the valves at the limit of the outward movement thereof. A suitable finger-piece such as the bail 9 is connected to the upper disk 4 and extends slightly beyond the mouth of the bottle, the two arms of the bail preferably operating within notches 14 formed in an annular flange 15 projecting inwardly from the mouth of the bottle. This bail 9 forms a means whereby the disks 4 can be moved vertically to control the valve 10 which has an operative connection with the lower disk 4 and normally bears against the lower face of the flange 2 in such a manner as to close the opening 3 defined thereby and prevent any evaporation or accidental spilling of the contents of the bottle. For the purpose of connecting the valve 10 and lower disk 4 the latter has an arch member 11 secured to the lower face thereof and carrying a pendent arm 12 which extends through the opening 3 and connects to the valve 10. It will thus be apparent that when the finger-piece or bail 9 is pressed inwardly the valve 10 is moved away from the opening 3 so that when the bottle is inverted or properly tilted the contents thereof will find a ready outlet. interposed between the flange 2 and the lower disk 4 is a coil spring 13 which normally operates to force the lower disk 4 outwardly and thereby draw the valve 10 upwardly against the flange 2 in which position it closes the opening 3.

In the manufacture of the device it is to be understood that the valve carrying frame may be either molded within the bottle or mounted 'within the same in any desired manner.

Having thus described the invention, what is claimed as new is:

1. In a device of the character described, the combination of a receptacle formed with a neck, a disk movably mounted within the neck, a valve carried by the disk, a fingcnpiece for operating the disk, a valve mounted Within the neck, and means carried by the disk for operating the second mentioned valve.

2. In a device of the character described, the combination of a receptacle formed with a neck, a disk slidahly mounted within the neck, a valve carried by the disk, a bail connected to the disk and extending beyond the mouth of the neck, a second valve mounted within the neck, and means carried by the disk for operating the second mentioned valve.

3. In a device of the character described, the combination of a receptacle formed with a neck having an annular flange projecting inwardly therefrom and defining an outlet opening, a disk slidahly mountedwithin the neck, a valve carried by the disk, an arm pendent from the disk and passing through the opening defined by the said flange, a valve carried by the arm and adapted to close the opening, and a finger-piece connected to the disk.

4. In a device of the character described, the combination of a receptacle formed with a neck having an annular flange projecting inwardly therefrom and defining an outlet opening, a disk slidably mounted within the neck, a valve carried by the disk, a second valve for closing the outlet opening defined by the said annular flange, connecting means between the disk and the second mentioned valve, :1 spring interposed between the flange and the disk whereby the latter is caused to normally seat the second mentioned valve, and a finger-piece connected to the disk.

In a device of the character described, the combination of a receptacle formed with a neck, a pair of spaced disks slidably mounted within the neck, connecting means between the disks, a valve carried by each of the disks, a valve mounted within the neck and having an operative connection with the spaced disks, and means for moving the spaced disks to operate the last mentioned valve.

6. 111 a device of the character described, the combination of a receptacle formed with a neck, a valve controlling the flow through the neck, a valve carrying frame movably mounted within the neck, a valve carried by the said frame and also controlling the flow through the neck, and connecting means between the valve carrying frame and the first mentioned valve.

In testimony whereof I aflix my signature in presence of two Witnesses. I
